> You need... I submit a counterexample of the huge network of Tesla superchargers that can do the job quite well with the NACS connector. maximum power output of 600 kW and a maximum current of 615A at 1,000V https://www.notateslaapp.com/news/1269/tesla-v4-superchargers-power-design-and-cable-length-revealed https://www.notateslaapp.com/news/1269/tesla-v4-supercharger... The practical limits are based on the cars and their batteries, not the charge port.

Supercharging, yeah. But you (or rather "everyone") won't constantly be supercharging. You'll mostly do it at home or at your office. 7kW :)

  Places where you don't need a fast charge? Overnight at home. From arrival to lunch at work. After lunch to quitting time. And even those times assume you drive more than 50 miles/day, which most folks don't. What was the problem again?

    While not the norm, 100km each way is not an unusual commute (I did that for years). With winter driving, long days out and long commutes, I suppose you could get to a point where 7kW AC slow-charging does not cut it, and having room for cheap upgrades don't hurt. You want to charge as slow as possible for your need, but needs do vary.

    Why would you consciously pick 7kW over 20+ just because of a sleeker connector? > What was the problem again Why would I want to wait for more than I have to? e.g. I forgot to charge during the night and need to go on a trip in a few hours. Now I need to find a fasts charger and pay for it instead of charging at home, why exactly?

>The practical limits are based on the cars and their batteries, not the charge port. You're referring to DC fast charging. For AC charging the NACS is limited to single phase. This is a charge port thing, not the car or battery. Which doesn't matter much in the US, but it does in Europe.
